In the News: Guar Gum in Hydraulic Fracking Fluid

Recently, the New York Times and other news outlets have reported that many poverty stricken areas in India have been the unwitting beneficiaries of a much needed financial boom from a very unlikely source -- guar beans, a small hard legume. The reason for this recent demand for the bean (or more specifically for the powder or concentrate produced from milling the bean) is similarly to its use as a thickening additive in ice cream, guar has become an essential ingredient in most hydraulic fracturing fluids by increasing viscosity. Below please find additional resources discussing the role of guar in fracking fluids.
